HSTS preloading, public key pinning and Chrome

I recently discovered Chrome's net-internals. Among other interesting things, there is a tab about HTTP Strict Transport Security (HSTS). Also, introduced with version 12/13, Chrome now has HSTS preloading and public key pinning. These two features helps improve online security:

• HSTS preloading: browser already knows if a site has to be contacted via HTTPS only. For instance, it ensures users go to https://site even if they type http://site. This protects against MITM attacks when reaching http://site for the first time (see how sslstrip strips the "s" of https).
• public key pinning: certificate chain must include a whitelisted public key. For instance, it ensures only whitelisted Certificate Authorities (CA) can sign certificates for *.example.com, and not any CA in your browser store.

Twitter Archiver

Twitter is great to get and share information, quickly. But it is all web 2.0 and you cannot use a simple cat or grep to view or search your tweets. I would like to have tweets saved in simple text format: date, user, text. Also, I would like a simple program to give me the list of followers/following of a user.

Fortunately, Twitter provides a web API and people started to implement it in different languages, like Mike Verdone (@sixohsix) and his great Python Twitter Tools.

So here comes twitter-archiver and twitter-follow, python programs added to Python Twitter Tools to archive any public timeline of tweets in simple text format and to view the list of following/followers of a user.
